Firefox uses 3-4x times as much memory as Chrome on animated image test case
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:9.0a1) Gecko/20110827 Firefox/9.0a1 Build ID: 20110827030801 Steps to reproduce: 1. Download the archive http://dl.dropbox.com/u/11652751/1.rar - it containts a pure html page with a ton of gifs. It's about 135mb in the packed state 2. Unrar the archive 3. Open the page inside of it 4. Watch memory consumption by firefox process Actual results: +650mb instantly increased RAM consumption Expected results: Chrome eats +170mb in that case
Summary: Too much memory consumption on the page with a lot of images → On the pages with a lot of images firefox consumes trice more memory then expected
Status: UNCONFIRMED → NEW
Component: General → ImageLib
Ever confirmed: true

Summary: On the pages with a lot of images firefox consumes trice more memory then expected → Firefox uses 3-4x times as much memory as Chrome on animated image test case
Presumably a duplicate of the bug on us decoding all frames of an animated gif....
Whiteboard: [MemShrink] → [MemShrink] DUPEME
Yeah, that's probably part of it. Chrome is also using less CPU than us, which makes me think that they're only animating the GIFs in view, but I didn't investigate much.
I've added bug 666446 as a blocking of this one, I don't understand if they are the same or not.
Depends on: 666446
That bug will help with the CPU usage here. It may or may not help with the memory usage (I didn't read the patches in detail).
Whiteboard: [MemShrink] DUPEME → [MemShrink:P2] DUPEME
Apparently bug 595671 will allow us to discard images.
[Clearing dependency on bug 666446, since that bug's not intended to help with memory usage as khuey suggested in comment 4]
No longer depends on: 666446
